A member of the female sex who adorns herself prodominantly in clothing too small for herself, creating an effect of her figure spilling out over the top of her pants, resembling the top of a muffin. Muffin tops are generally unaware of their condition, and typically even believe that they are MORE attractive than non-muffin tops. These females are very easily spotted in nearly all social events, and the muffin tops even parade themselves about in a way to advertise their willingness to participate in sexual activity with willing members of BOTH sexes. Most of the time, muffin tops can be found in the pressence of and under the influence of alcohol and other substances.

"look at jessica, in those pants she is a total muffin top, they must be at least 2 sizes too small, and her fat stomache is spilling out all over the place!"

when a girl has pants on that are like 3 sizes to small and there fat hang over the edge. It really doesnt help when they wear tight shirts that hug your skin so your muffin tops hang out of the bottom.

"SICK, Look at Marks girlfriends muffintops. He must like muffins, cause thats NASTYYY."
